To all whom if may concern:

Be it known that I, Jnnnv A. Pnnsco'r'r, a citizen of the United States, and a resident of Steele, in the county of Kidder and State of North lakota, have invented a new and Improved Bental Disk-Holder, of which the following a full, clear, and exact description.

My invention relates to dent-al disk holders and the object thereof is to provide a simple and inexpensive device whereby in a single structure means may be provided for conveniently holding in accessible position a supply ot disks ot' various sizes.

Reference is to be had to the accompanying dran-:ings orming a part of thisrspecnif-r cation, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a perspective view of my device in operative position; Fig. 2 is a vertical sectional view thereof, on the line 2 2 et Fig. 1; Fig. 3 is a. perspective view of one of the inagazi .esg F ig. s'. is a similar view showing a modified forni oi outlet; Fig. 5 vsectional view or this forni. l

lily device may be convenient-ly made of two pieces of metal, one portion of which contains the semicylindrical enibossings 1, 2, 3, ft, t3, togetherwith the offset end portions 7, 8, provided with suitable holes to receive fastening means 9, such as screws or tacks; this forms,` in etiect, one halt of my device. The other halt is conveniently formed of another pieceof sheet metal having the 'semicylindricalembossings 10, 11, 12, 13, 14, and 15, which are adapted to be juxtaposed to the portions 1, 2, 3, 4, 5, 6, whereby a series of chambers or magazines are formed, shown particularly in Fig. 1. The rigidity of the structure is maintained by suitable longitudinally extending portions 16, 17, 18, which lie closely adjacent similar portions provided on one of the pieces of metal and which lie closely adjacent similarly shaped portions on the other piece of metal, this second piece of metal being also pro-vided with offset end portions similar to the end portions 7, 8, and provided with holes which register Awith the holes in the end portions 7, 8, for the reception of the screws or tacks 9. It will he noted that the diameter of each of these magazines or pockets increases from right to left whereby they may contain a large The bottom portion of each of these pockets or magazines consists of a pair of forwardly extending fingers 20, 21, preferably integral with one of the pieces of metal from which the pockets are formed, these ngers extending from a down-turned portion 22 carried by this piece of metal, there being a suitable opening 23 between each of the lingers and the lower end portion of each of the embossings 1, 2 3, 4, 5, 6, being removed for a short distance, as at 24, whereby a'disk may loewithdrawn from thebottom of any pocket by merely bringing the finger into the opening 23 and drawing the disk for- 70 wardly from the bottom of the supply contained therein. It may be desirable in some instances to provide these pockets or vmagazines with means whereby a pocket of a given diameter may be adapted to vcontain disks of varying thicknesses and in order to meetl such a demand l have provided the constructionshown in Figs. 4 and 5. The lower end portion of each of the embossings 1 to 6 inclusive is removed, as at 24', each of so these embossings being providedon its front portion and adjacent the lower end thereof,

with the threaded stud 30 on which a suitable thumb nut 31 engages. A circular plate 32 is provided with a slot 33 through which 85 the stud 30 passes, the curvature of this plate being the same as'that of each of the l embossings and the nut 31 being adapted .to be tightened, whereby this plate may be held in close contact on each'pocket-or magae0 zine and at a varying distance from the bottom thereof, whereby its position may be changed in order to admit of the free withdrawal of disks 'of diiierent thicknesses.

` The disks in each of the' pockets or lnaga- 95 zines are maintained in suitable position therein for easy withdrawal by means of a small weight 40 of substantially the same diameter as the pocket in which it is used. The use of such a weight in keeping the disks closely packed tends to lprevent the same from warping or curling while lying within the magazine, the weight being of such a mass that the disks are held in substantially horizontal 'position and with suf- 105 -ticient pressure against the fingers 20, 21, that when one is desired to be withdrawn the pressure applied thereto in order to withdraw it will not be suhicient to raise the pack of disks upwardly within the pocket.

"it is obvious that many changes may be number of dental disks of various sizes.
